To use this dataset, you need to install ConvLab-3 platform first. Then you can load the dataset via:

from convlab.util import load_dataset, load_ontology, load_database

dataset = load_dataset('crosswoz')
ontology = load_ontology('crosswoz')
database = load_database('crosswoz')

Dataset Summary

CrossWOZ is the first large-scale Chinese Cross-Domain Wizard-of-Oz task-oriented dataset. It contains 6K dialogue sessions and 102K utterances for 5 domains, including hotel, restaurant, attraction, metro, and taxi. Moreover, the corpus contains rich annotation of dialogue states and dialogue acts at both user and system sides. We also provide a user simulator and several benchmark models for pipelined taskoriented dialogue systems, which will facilitate researchers to compare and evaluate their models on this corpus.

• How to get the transformed data from original data:
  • Run python preprocess.py in the current directory. Need ../../crosswoz/ as the original data.
• Main changes of the transformation:
  • Add simple description for domains, slots, and intents.
  • Switch intent&domain of General dialog acts => domain == 'General' and intent in ['thank','bye','greet','welcome']
  • Binary dialog acts include: 1) domain == 'General'; 2) intent in ['NoOffer', 'Request', 'Select']; 3) slot in ['酒店设施']
  • Categorical dialog acts include: slot in ['酒店类型', '车型', '车牌']
  • Non-categorical dialogue acts: others. assert intent in ['Inform', 'Recommend'] and slot != 'none' and value != 'none'
  • Transform original user goal to list of {domain: {'inform': {slot: [value, mentioned/not mentioned]}, 'request': {slot: [value, mentioned/not mentioned]}}}, stored as user_state of user turns.
  • Transform sys_state_init (first API call of system turns) without selectedResults as belief state in user turns.
  • Transform sys_state (last API call of system turns) to db_query with domain states that contain non-empty selectedResults. The selectedResults are saved as db_results (only contain entity name). Both stored in system turns.
• Annotations:
  • user goal, user state, dialogue acts, state, db query, db results.
  • Multiple values in state are separated by spaces, meaning all constraints should be satisfied.

6 domains: ['景点', '餐馆', '酒店', '地铁', '出租', 'General']

• cat slot match: how many values of categorical slots are in the possible values of ontology in percentage.
• non-cat slot span: how many values of non-categorical slots have span annotation in percentage.
